Precautions for Class A laminar flow vehicles
Precautions for Class A laminar flow vehicles(I) Personnel requirementsTraining requirements Operators must undergo professional training and be familiar with the working principle, operating specifications, and safety precautions of Class A laminar flow vehicles. The training content includes but is not limited to the airflow organization, cleaning and disinfection methods, and item placement principles of laminar flow vehicles. Operators should be assessed regularly to ensure that they can operate the laminar flow vehicle correctly. The assessment content may include practical operating skills, familiarity with operating specifications, etc. Personal hygiene Before entering the operating area, operators should change into clean work clothes and work shoes, and wear hats, masks, and gloves. Work clothes should be made of materials that are not easy to generate static electricity and do not drop fibers. Operators should keep their hands clean and use appropriate disinfectants to disinfect their hands before operation. For example, use hand sanitizer containing chlorhexidine gluconate to wash your hands for at least 30 seconds. (II) Equipment maintenance and troubleshooting Regular maintenance Perform comprehensive maintenance on Class A laminar flow vehicles regularly according to the equipment manufacturer's recommendations. This includes checking the operating status of the fan, replacing high-efficiency filters, calibrating anemometers, etc. Generally speaking, the replacement cycle of high-efficiency filters is about 1-2 years, depending on the use environment and frequency. Regularly check the electrical system of the laminar flow cart, including checking whether the wire connection is firm and whether the electrical components are normal. At the same time, check and lubricate the mechanical parts of the equipment, such as door locks, casters, etc., to ensure their normal operation. Fault handling If the laminar flow cart fails during operation, such as the fan suddenly stopping, the wind speed is abnormal, the ultraviolet sterilization lamp is not on, etc., the operation should be stopped immediately and the items in the laminar flow cart should be properly handled. For example, transfer the medicine to other equipment or areas that meet the clean requirements. For some simple faults, such as loose power cords and blown fuses, trained operators can perform emergency treatment according to the maintenance manual of the equipment. However, for complex faults, such as fan damage and high-efficiency filter leakage, professional maintenance personnel should be contacted in time for maintenance. (III) Safety precautions Electrical safety Class A laminar flow carts should use power sockets that meet safety standards and have good grounding. Avoid using laminar flow carts in humid environments to prevent electric shock accidents. Regularly check the laminar flow vehicle's electrical circuits for damage, aging, etc. If an electrical fault is found, the power supply should be cut off before maintenance to ensure the safety of the maintenance personnel. UV safety When the UV sterilization lamp in the laminar flow vehicle is turned on, the operator should avoid looking directly at the UV light source to prevent UV damage to the eyes and skin. Protective devices can be installed outside the UV lamp of the laminar flow vehicle, or obvious warning signs can be set when the UV lamp is turned on. After the UV sterilization lamp is turned off, wait for some time (usually 15-30 minutes) and wait for the ozone to decompose before turning on the laminar flow vehicle for operation. Because ozone is produced during UV sterilization, high concentrations of ozone are harmful to the human body. |
